BARB-WIRE FENCE.

SPECIFICATION forming part of Letters Patent No. 380,388, dated April 3, 1888.

Application filed October 28, 1887. Serial No. 253,586. (No model.)

To aZZ whom, it may concern:

Be it known that I, J. WooL GRISWOLD, of Troy, Rensselaer county, New York, have inventedanew and useful Improvement in Barb- Wire Fences, of which the following is a specification.

My invention relates to the combination, with a two-stranded wire cable, of the barbpiece hereinafter set forth.

The object of my invention is to produce a novel and simple combination of fence cable and barb wherein the barb is held in place between the strands, and wherein the strands are not cut, slit, or in any wise altered to receive said barb, nor the barb itself twisted or wrapped about either strand. The advantages of this combination are that no skill or special ma chinery is required to make it. Any one can apply the barb to the cable, even, if desired, after the latter has been strung as fencing. Barbs that have fallen out or become broken off can easily be replaced without the use of any special tools.

In the accompanying drawings, Figure 1 is a bottom view of my combination of barb and cable. Fig. 2 is atop, Fig. 3 is a side, and Fig. 4 a sectional, view of the same, the section in Fig. 4 being made on the line a: w of Fig. 2.

Similar letters of reference indicate like parts.

A and Bare two strands of a wire cable twisted together in the usual manner. 0 is the barb-piece, of sheet metal, pointed at both ends, which is first bent so as to form a loop, as D. The ends F F of the barb-piece G are inserted between the strands A B and afterward are separated or spread out so as to protrade in opposite directions, as best shown in Figs. 1 and 4.

It will be apparent that the loop D prevents the barb-piece G from passing between the strands in one'directiomwhile the spread-out ends F F prevent it from being displaced in the other direction. In this way the barb-piece 5 becomes very securely held between the strands without being turned or wrapped around either of them, or around the cable itself. At the same time it is very easily applied. Inasmuch as the barbpiece is jammed between 5c the cable-strands, it will be obvious that any stretching of the cable tends to cause it to be grasped all the tighter,while, on the other hand, the size of the loop is such that the strands may become widely separated before the loop 5 5 can pass between them.

, I am aware that it is notnew to combine a sheet-metal barb having a loop and projecting points with a metal strip through an opening or slit in which said points are thrust and then opened, and such a combination I do not herein claim.

It is obvious that the aforesaid combination is objectionable, because the metal strip must be cut to allow of the attachment of the barb. This weakens the strip in direct proportion to the number of barbs affixed, and also involves the use of special tools for making the openings in the strip, and the operation of producing such openings constitutes a separate step in the process of manufacture.

I claim-- In combination with a twostranded wire cable, a barb-piece of thin sheet metal pointed at both ends, bent double to form a loop, and 7 5 held between said strands, the loop being located on one side of said strands and the sepa rated ends of said barb-piece on the other, substantially as described.
